"The Catholic Faith is this, that we worship one God in the Trinity, and the Trinity in unity, neither confounding the persons nor dividing the substance. For there is one person of the Father, another of the Son, and another of the Holy Spirit. But the Godhead of the Father, of the Son and of the Holy Spirit is one, the glory equal, and the majesty co-eternal.
"Such as the Father is, such is the Son, and such is the Holy Spirit. The Father uncreated the Son uncreated and the Holy Spirit uncreated. The Father infinite, the Son infinite and the Holy Spirit infinite.
"The Father eternal, the Son eternal and the Holy Spirit eternal. Yet they are not three eternals, but one eternal. As also they are not three uncreateds nor three infinites, but one uncreated and one infinite. Likewise the Father is almighty, the Son is almighty and the Holy Spirit is almighty.
"Yet they are not three almighties, but one almighty. Likewise the Father is God, the Son is God and the Holy Spirit is God. Yet they are not three gods, but one God.
"Likewise the Father is Lord, the Son is Lord and the Holy Spirit is Lord. Yet they are not three lords, but one Lord.
"For just as we are compelled by the Christian truth to acknowledge each person by himself to be God and Lord, so we are forbidden by the Catholic religion to say there are three gods or three lords.
"The Father is made by none, neither created nor begotten. The Son is from the Father alone; not made nor created, but begotten. The Holy Spirit is from the Father and the Son; not made nor created nor begotten, but proceeding.
"So there is one Father, not three fathers; one Son, not three sons; one Holy Spirit, not three holy spirits. And in this Trinity nothing is before or after, nothing is greater or less; but the whole three persons are co-eternal together and co-equal.
"So that in all things, as aforesaid, the unity in Trinity and the Trinity in unity is to be worshipped. Whoever, therefore, wishes to be saved, let him think thus of the Trinity.
"It is also necessary for salvation to believe Faithfully the Incarnation of our lord Jesus Christ. The right Faith, therefore, is that we believe and confess that our lord Jesus Christ, Son of God, is God and man. God, of the substance of the Father, begotten before the ages; and man, of the substance of his mother, born in the world.
"Perfect God, perfect man, subsisting of a rational soul and human flesh. Equal to the Father according to his Godhead, less than the Father according to his humanity. Although he is God and man, he is not two, but one Christ.
"One, however, not by conversion of the Godhead into flesh, but by the taking of humanity into God. One altogether, not by confusion of substance, but by unity of person. For as a reasoning soul and flesh is one man, so God and man is one Christ.
"He suffered for our salvation and descended into hell. On the third day he rose from the dead. He ascended into heaven and sits at the right hand of God the Father almighty. Thence he shall come to judge the living and the dead. At his coming all shall rise again with their bodies, and shall give an account of their own deeds. Those who have done good shall go into eternal life, but those who have done evil shall go into eternal fire.
"This is the Catholic Faith. Unless a person believes it faithfully and firmly, he cannot be saved."
This creed was decreed ex cathdera by Pope Eugene IV at the Council of Florence in AD 1439. It is infallible and an objective and absolute truth. Every single member of the whole human race must know and believe the above in order to be said to hold the Catholic Faith, in order to have a chance to be saved. To deny any article of it at all, including the first and last phrases, is heresy.
Any person who is unaware of any of the points of doctrine contained in this Creed is outside the Church and still in his sins. While there is such a thing as material heresy - that is heresy without the will to oppose the Church, and it does not always mean a person is in sin, any incorrect belief or lack of knowledge against the above dogmas means certain damnation, unless it is corrected before death, as it is clearly defined:
"Whoever wills to be saved, before all things it is necessary that he holds the Catholic Faith. Unless a person keeps this Faith whole and undefiled, without doubt he shall perish eternally. The Catholic Faith is this, [the articles] This is the Catholic Faith. Unless a person believes it faithfully and firmly, he cannot be saved."
